MAX2079 : Low-Power, High-Performance, Fully Integrated Octal Ultrasound Receiver
Breakthrough Levels of Performance for High-Channel-Count,
Cart-Based and Portable Ultrasound Imaging Equipment
The MAX2079 fully integrated octal ultrasound receiver is optimized for high channel count,
high-performance portable and cart-based ultrasound systems. The easy-to-use integrated
receiver allows the user to achieve high-end 2D and Doppler imaging capability using substantially
less space and power. The highly compact low-noise amplifier (LNA), variable-gain amplifier (VGA),
anti-alias filter (AAF), analog-to-digital converter (ADC), and digital highpass filter (HPF) achieve
an ultra-low 2.8dB noise figure at RS = RIN = 200Ω with a very low 120mW per channel power dissipation at 50Msps.
The full receive channel has been optimized for second-harmonic imaging with an exceptional 76dBFS SNR over
a 2MHz bandwidth, and -70dBc second-harmonic distortion at fRF = 5MHz over the full receiver gain range.
Near-carrier dynamic range has also been optimized for exceptional pulsed and color-flow Doppler performance
under high-clutter conditions. The bipolar front-end and CMOS ADC achieve an exceptional near-carrier SNR of 137dBFS/Hz
at 1kHz from a 5MHz tone for excellent low-velocity Doppler sensitivity.
The device also includes an octal CWD beamformer for a full Doppler solution.
Separate mixers for each channel are available for optimal CWD sensitivity.
